Serial No. 536,470'

c claims. (ci. 226-77) This invention relates to improvements in bottlefillers and particularly to combined bottle fillers and cappers. l

In this connection attention isA directed to my copending applicationfor patent, filed April 29,

1930, entitled Bottle llers and cappers and bearing Serial Number448,224.

The principal object ofthe invention is to simplify vthe mode ofoperation'and the means for iilling ,l and capping bottles. n

Another object is to prevent leakage; at the filler between the bottlefilling operations.

A further object is to provide an improved holding, clinching andcrimping means for crown caps. l

Other objects and advantages will appear as the description progresses.

In this specification and the accompanying drawings the invention isdisclosed in its preferred form. It is to be understood', however, thatitis not limited to this form because it may be embodied inV other formsYwithin the spirit of the claims following the description.

In the two sheets of drawings:

Fig. 1 is a vertical section of a combined iller and capper constructedin accordance with this invention.

Fig. 2 is a similar View of the same in the -tle lling position.

Fig. 3 is a similar view of thesame in tle capping position.

Fig. 4 is a similar view of a modified form of portable bottle ller inthe closed position.

Fig. 5 is a similar View of the same in the bottle lling position.

Fig. 6 is a side elevation of the modiiied form complete with the handleand vent.

In detail the construction illustrated in the drawings, referring toFig. 1, comprises the outer shell 1, having the chamfered opening 2 latthe bottom. Its upper portion or head 3 has the threadedcentral openingtherethru to receive the threaded end 4 of the plunger of the cappingmachine. The interior opening of the shell has the annular shoulder 5and is recessed at 6 and vented through the head at 'l to receive thenipple 8. The side of the shell is slotted at 9 to clear the thebotfiller nipple 10. This shell 1 rises and falls withA the plunger stud4 to cap the bottle X resting upon the base of the capping machine inthe usual manner.

The iiller valve mechanism consists of an inverted elastic cup 11, oftough vulcanized rubber stock. The annular plug 12 of softer elastic 5stock is inserted in the bottom of the cup 11 which it ts snugly andwith which it' forms ahermetic bond. The parts 11-12 coact as a unit toform` the chamber 13. The valve seat 14 is formed in the bottom oftheplug 12. The vvalve lfcooper-I ates with the seat 14 and has the tubularstem,

16, extending thru the top 17 of the cup 11,. which it engages betweenthe ange l8--19. The elasticity of the walls and the top 16 of the cup11 normally pullthe valve 15 snugly" against. the soft seat 14. Thevalve and stem 15-16 may be formed of non-corrosive metal, bakelite orany suitable material. Y Y

The hollow collapsible cushion 20 is'set vwithin the recess 6 and isprovided withY alined perforations 21-22 communicatingwith the vent 7and the tubular stem 16.

The annular ring 23 surrounds Athe plug 12 tof which it adheres andstops against `the shoulder 5.

The .bottle Xis placed in the capping `machine under the ,plunger 4 asinFig. 2. Vi/hen the plunger descends, the ring 23Y engages theY tcp ofthe bottle which pushes the ring up to the stop shoulder 5. This raisesthe cup 11 until the end 19 of the stem 16 impinges on the cushion 20.The resistance of the cushion depresses and collapses the top 17 of thecup 1l. The completion of the upward movement of the ring 23 thus raisesthe seat 14 off the valve 15. As the plunger 4 rises the valve 14-15closes as in Fig. 1.

The crown cap Y is placed on top of the bottle under the bottom 2 of theshell and the plunger 4 again forced down 'to clinch the cap onto theneck of the bottle, inthe usual manner. The presence of the cap carriesthe valve 15-16 upward, which compresses the cushion 20. The re"-sistance of the cushion is sufficient to depress or crimp the center ofthe cap Y, which further ccm- -presses the corl; gasket Z between thecap and the mouth of the bottle insuring perfect sealing of the bottleclosure.`

This invention operates substantially as follows: The liquid flows thruthe nipple 10 into the chamber 13 and is stopped by the valve 14-15 asin Fig. 1. If the liquid is siphoned, the flow can be started byapplying suction to the vent nipple 6 after the bottle X is inserted inthe machine. A Insertion of the bottle as in Fig. 2 opens the valve14-15, permitting the liquid to ow into the bottle. The liquid isdirected against the sides of the bottle clown which it flows, while theair impounded in the bottle flows upwardthru the tubular valve stem 16and escapes at the vent 7. If foaming liquids are being handled theywill OW into the bottle Without efervescing, if directed against thesides of the bottle as stated, and the impounded air is given a freeoutlet. If there is any mingling of such liquid with the outgoing air,regurgitation is set up and filling of the bottle is prevented.

When the pressure against the mouth of the bottle is removed theresilient Walls and top 17 of the cup 11 expand and draw the valve 15against its seat 14. This seat being oi soft rubber it insures a perfectstopping of the liquid, even in the presence of ordinary obstructivesolid particles suspended in the liquid, which cause an after drip atthe filler when other forms of valves are used. The extended annulus ofthe valve at 24. of soft rubber seals the mouth of the bottle againstoverflow during the lling operation, see Fig. 2.

In addition to the mechanical effectiveness and simplicity of theresilient chamber 13 it protects the liquid from contact with the metalparts of the apparatus. All the parts contacting the liquid canbe ofsoft and hard rubber respectively' and easily maintained in a sanitiarycondition. The modified form of this invention shown in Figs. 4-5-6 issimilar in construction and mode of operation to that previouslydescribed, except that the capping mechanisms are omitted. Foridentication the various parts will be given the same referencecharacters previously used, with the addition of the character zv. Thismodification is especially useful for rapidly lling bottles arranged enmasse. The handle 4J; is substituted for the plunger 4 through which thetubular vent 7a: extends and is bent laterally so that the hand of theoperator will not close it. When the ring 23.1: is pressed down upon theneck of the bottle the Walls of the chamber 13 compress and open thevalve 14m-15x. Lifting the handle 4.1; automatically closes the valve.The shell la: merely acts to guide the top of the bottle under the valveand to give stability to the device in operation.

Having thus described this invention what is claimed and desired tosecure by Letters Patent is:

1. A filler including a shell having an internal shoulder, resilientwalls within said shell forming a chamber and having a valve seattherein, a ring encircling said seat and adapted to engage saidshoulder, a valve engaging said seat and having a hollow stem engagingsaid Walls.

2. A ller including a shell having a vent therefrom; a resilient Wallwithin said shell forming a chamber with a valve seat therein; a valveengaging said seat and having a hollow stem engaging said wall and saidshell and communieating with said vent.

3. A ller including a' shell; a resilient wall within said shell forminga chamber with openings in its opposite sides respectively; a valveengaging one of said openings and having a stem iixed in the oppositeopening and a cushion interposed between said shell and the end of saidstem.

4. A filler including a shell with a top Vent and a side opening andhaving an internal shoulder; a wall within said shell forming a chamberhavin openings in its opposite sides; a valve engaging one of saidopenings and having a hollow stem communicating with said vent andengaging the other opening, a cushion interposed between said stem andthe top of said shell and a nipple eX- tending through a side openingand communicating with said chamber.

5. A llerkincluding a shell; a coinpressible wall, and a collapsible topwithin said shell forming a chamber with a valve seat therein; a valveengaging said seat and having a stem engaging said top and said shell.

6. A ller including a shell having a vent therefrom; a compressible Walland a collapsible top within said shell forming a chamber with a valveseat therein; a valve engaging said seat and having a hollow stemengaging said top and said shell and communicating with said vent.
